So, i read the starting message and the according subject "How far are we from quantum cryptography?" and when i continued reading the follwing mails i wondered if that even answered the question, since quantum computing != quantum cryptography Ccommon 'quantum cryptography' is basicly a public-key-system with quantum-states being send from Alice to Bob, i believe we already do have quite some research on that. Using photons as quantum states and fibreglass to transfer the photons there have been successful implementations over > 100 km. In theory there also are some 'secure' protocolls... I gues we will be seeing quantum cryptography in action prior to quantum computation. _______________________________________________ cryptography mailing list [email protected] http://lists.randombit.net/mailman/listinfo/cryptography
